ABSTRACT
To determine the locations of congenital cholesteatomas and to elucidate the relationship between ossicular anomalies and congenital cholesteatomas, cholesteatomas from our patients and those reported in the Japanese literature were investigated. We analyzed 40 ears with congenital cholesteatomas (38 patients) experienced by us during the past 9 years. Our criteria of congenital cholesteatoma were as follows 1. The tympanic membrane manifests neither retraction, perforation, nor granulation, 2. There is no continuity between the tympanic membrane and the matrix of a cholesteatoma. Twenty patients with past histories of otitis media were included. Thirty-three patients (87%) were males and 2 had bilateral congenital cholesteatomas. The ages of the patients ranged from 2 to 46 years (mean 10.7). A survey of the Japanese literature revealed 55 additional cases of congenital cholesteatoma reported by others.
